Pull io_uring fixes from Jens Axboe:
 "Two different fixes in here:

   - Fix for a potential NULL pointer deref for links with async or
     drain marked (Pavel)

   - Fix for not properly checking RLIMIT_NOFILE for async punted
     operations.

     This affects openat/openat2, which were added this cycle, and
     accept4. I did a full audit of other cases where we might check
     current->signal->rlim[] and found only RLIMIT_FSIZE for buffered
     writes and fallocate. That one is fixed and queued for 5.7 and
     marked stable"

History
Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
